科士达后备式UPS电源与科士达在线式UPS电源的不同之处

科士达后备式UPS电源与科士达在线式UPS电源的工作方式有何区别在于：

A.交流输入正常时的工作方式不同

C.科士达后备式UPS正常工作时，交流输入经过静态开关直接到负载

D.科士达在线式UPS正常工作时，交流输入则经过整流后，再通过逆变变成交流电，再为负载供电

科士达后备式UPS电源：平时处于蓄电池充电状态，在停电时逆变器紧急切换到工作状态，将电池提供的直流电转变为稳定的交流电输出，因此后备式UPS也被称为离线式UPS。科士达后备式UPS电源的优点是：运行效率高、噪音低、价格相对便宜，主要适用于市电波动不大，对供电质量要求不高的场合，比较适合家庭使用。然而这种UPS存在一个切换时间问题，因此不适合用在关键性的供电不能中断的场所。不过实际上这个切换时间很短，一般介于2至10毫秒，而计算机本身的交换式电源供应器在断电时应可维持10毫秒左右，所以个人计算机系统一般不会因为这个切换时间而出现问题。后备式UPS一般只能持续供电几分钟到几十分钟，主要是让您有时间备份数据，并尽快结束手头工作，其价格也较低。对不是太关键的电脑应用，比如个人家庭用户，就可配小功率的后备式UPS。
 

What's the difference between the back-up UPS power supply and the on-line UPS power supply?
A. Different ways of working when AC input is normal
When C. Costa backup UPS works normally, AC input goes directly to load through static switch.
D. Costa on-line UPS works normally, the AC input is rectified, then converted into AC through inversion, and then supply power to the load.
Corstal backup UPS power supply: Usually in the battery charging state, when the power failure, the inverter emergency switching to the working state, the DC power provided by the battery into stable AC output, so backup UPS is also known as off-line UPS. Costa backup UPS power supply has the advantages of high efficiency, low noise and relatively low price. It is mainly suitable for the occasion where the fluctuation of electricity is not big and the quality of power supply is not high, and it is more suitable for family use. However, this UPS has a switching time problem, so it is not suitable for critical places where power supply can not be interrupted. But in fact, the switching time is very short, generally between 2 and 10 milliseconds, and the switched power supply of the computer itself should be able to maintain about 10 milliseconds when the power is cut off, so the personal computer system will not generally have problems because of this switching time. Backup UPS can only supply power for a few minutes to tens of minutes, mainly to give you time to back up data and finish the work at hand as soon as possible. The price is also lower. For less critical computer applications, such as personal home users, low-power backup UPS can be deployed.

科士达在线式UPS

正常用电时，经过由突波吸收滤波电路→交流电转换直流电电路→直流电转换交流电电路→并转换交流电输出供应负载，并同时对电池充电;一旦微处理器控制电路侦测到市电中断，则立即由电池放电→直流电转换交流电电路→并转换交流电输出供应负载使用。如果，微处理器控制电路侦测到UPS故障，此时科士达UPS会借由继电器(RELAY)跳至旁路(BYPASS)，由市电供应负载电力，并发出声响警告使用者。

科士达在线式UPS电源一直使其逆变器处于工作状态，它首先通过电路将外部交流电转变为直流电，再通过高质量的逆变器将直流电转换为高质量的正弦波交流电输出给计算机。在线式UPS在供电状况下的主要功能是稳压及防止电波干扰;在停电时则使用备用直流电源(蓄电池组)给逆变器供电。由于逆变器一直在工作，因此不存在切换时间问题，适用于对电源有严格要求的场合。科士达在线式UPS不同于后备式的一大优点是供电持续长，一般为几个小时，也有大到十几个小时的，它的主要功能是可以让您在停电的情况可像平常一样工作，显然，由于其功能的特殊，价格也明显要贵一大截。这种科士达在线式UPS比较适用于计算机、交通、银行、证券、通信、医疗、工业控制等行业，因为这些领域的电脑一般不允许出现停电现象

从原理上看，科士达后备式UPS和科士达在线式UPS的主要区别在于，后备式UPS在有市电时仅对市电进行稳压，逆变器不工作，处于等待状态，当市电异常，后备式UPS会迅速切换到逆变状态，将电池电能逆变成为交流电对负载继续供电，因此后备式UPS在由市电转逆工作时会有一段转换时间，一般小于10ms。

而科士达在线式UPS开机后逆变器始终处于工作状态，因此在市电异常转电池放电时没有中断时间，即零中断。在线式UPS，是指在输入市电正常时，科士达UPS的逆变器处于反向工作给蓄电池充电，在市电异常时逆变器立刻投入逆变工作，将电池组电压转换为交流电输出，因此在线式UPS也有转换时间。

Costa Online UPS
When using electricity normally, the supply load is converted from sudden wave absorption filter circuit to alternating current converting direct current circuit to alternating current converting direct current circuit to alternating current converting alternating current circuit, and the batteries are charged at the same time. Once the microprocessor control circuit detects the interruption of municipal electricity, the batteries are discharged immediately from batteries to alternating current converting alternating current circuit to alternating current output supply load. If the microprocessor control circuit detects a UPS failure, the Corstal UPS will jump to BYPASS by relay (RELAY), which supplies the load power from the municipal power supply, and issue a sound warning to the user.
The Corstal on-line UPS power supply keeps its inverters in working state. It first converts external AC to DC through circuit, and then converts DC to high-quality sinusoidal AC through high-quality inverters and outputs them to the computer. The main functions of on-line UPS under power supply condition are to stabilize voltage and prevent radio interference. When power failure occurs, standby DC power supply (battery group) is used to supply power to the inverters. Because the inverters are working all the time, there is no switching time problem, which is suitable for the occasion where there are strict requirements for power supply. One of the main advantages of Kosta online UPS is that the power supply lasts for a long time, usually for several hours, but also for more than ten hours. Its main function is to enable you to work as usual in the case of power outage. Obviously, because of its special function, the price is obviously expensive. This kind of on-line UPS is more suitable for computer, transportation, banking, securities, communications, medical treatment, industrial control and other industries, because these areas of computers generally do not allow blackouts.
In principle, the main difference between the backup UPS and the on-line UPS is that the backup UPS only regulates the voltage of the city power when the market power is available, and the inverters do not work and are in a waiting state. When the market power is abnormal, the backup UPS will switch to the inverted state quickly, and the battery power will be inverted into AC to continue to supply power to the load. Therefore, the backup UPS works from the city power to the inverted state. There will be a period of conversion time, generally less than 10 ms.
However, the inverters are always in working state after the on-line UPS is turned on, so there is no interruption time, i.e. zero interruption, when the battery is discharged abnormally. On-line UPS means that when the input power is normal, the inverters of Corstal UPS are in reverse operation to charge the batteries, and when the power is abnormal, the inverters are immediately put into inverters to convert the battery voltage to AC output, so on-line UPS also has conversion time.

科士达ups电源组成：

1、科士达UPS电源主板：是最终要的的核心部分，是保证各个功能运行最重要地方。当然对于ups电源主板也相对于控制系统，对于不同的功能使用的地方也都是不一样的主板。

2、科士达UPS电源：蓄电池是UPS用来作为储存电能的装置，它由若干个电池串联而成，其容量大小决定了其维持放电(供电)的时间。其主要功能是：

⊙市电正常时，将电能转换成化学能储存在电池内部。

⊙市电故障时，将化学能转换成电能提供给逆变器或负载;

3、动态旁路开关。动态开关为有触点开关，由接触器、断路器构成，靠机械动作完成转换，动态开关转换过程会有几十毫秒的供电中断，故不能应用于重要的负载场合，现代的UPS不间断电源已很少采用。

4、静态开关：静态开关又称静止开关，它是一种无触点开关，是用两个可控硅(SCR)反向并联组成的一种交流开关，其闭合和断开由逻辑控制器控制。分为转换型和并机型两种。转换型开关主要用于两路电源供电的系统，其作用是实现从一路到另一路的自动切换;并机型开关主要用于并联逆变器与市电或多台逆变器。所谓电子式静态转换开关，是将一对反向并联的快速晶闸管连接起来作为UPS不间断电源在执行由市电旁路供电至逆变器供电切换操作时的元件，由于快速晶闸管的接通时间为微秒级，同小型继电器毫秒级的转换时间相比，它只是小型继电器的千分之一左右。因此，依靠这种先进技术，可以对负载实现转换时间为零的不间断供电。正常工作时，只有逆变器供电回路或交流旁路电源回路之中的一路电源向负载供电。只有当科士达UPS电源需要执行由交流旁路电源供电至逆变器供电切换操作时，才会出现短暂的(约几毫秒~几十毫秒)两路交流电源在时间上重叠向负载供电的情况。静态开关可以将转换时间缩短到毫秒以下，甚至100μs以内，但损耗较大。

Costa UPS power supply composition:

1. Costa UPS power supply motherboard: is the ultimate core part, is the most important place to ensure the operation of each function. Of course, the UPS power motherboard is also relative to the control system, for different functions are also used in different motherboards.
2. Costa UPS Power Supply: Battery is a device used by UPS to store electric energy. It consists of several batteries connected in series. Its capacity determines the time it takes to maintain discharge (power supply). Its main functions are:
When the city electricity is normal, the electric energy is converted into chemical energy and stored in the battery.
When power failure occurs, chemical energy is converted into electrical energy and supplied to the inverter or load.

3. Dynamic bypass switch. The dynamic switch is a contact switch, which is composed of contactor and circuit breaker. It can complete the conversion by mechanical action. The dynamic switch conversion process will have tens of milliseconds of power supply interruption, so it can not be applied to important load occasions. Modern UPS uninterruptible power supply has rarely been used.
4. Static switch: Static switch, also known as static switch, is a contactless switch. It is an AC switch composed of two SCR in reverse parallel. Its closure and disconnection are controlled by a logic controller. It can be divided into two types: conversion type and parallel type. Conversion switch is mainly used in two-way power supply system. Its function is to realize automatic switching from one way to another. Parallel switch is mainly used for parallel inverters and municipal or multi-inverters. The so-called electronic static switching switch is to connect a pair of reverse parallel fast thyristors as UPS uninterrupted power supply components when switching operation from city bypass power supply to inverter power supply. Because the switching time of fast thyristor is microsecond, compared with the millisecond switching time of small relay, it is only about one thousandth of that of small relay. Therefore, relying on this advanced technology, the load can be converted to zero uninterrupted power supply. In normal operation, only one of the inverters power supply circuit or AC bypass power supply circuit supplies power to the load. Only when the Kosta UPS power supply needs to perform the switching operation from AC bypass power supply to inverter power supply, will there be a short time (several milliseconds to tens of milliseconds) when the two AC power supply overlaps to the load in time. Static switches can shorten the conversion time to less than milliseconds, or even less than 100 microseconds, but the loss is large.

5、逆变器：通俗的讲，逆变器是一种将直流电(DC)转化为交流电(AC)的装置。它由逆变桥、控制逻辑和滤波电路组成;

6、整流器：整流器是一个整流装置，简单的说就是将交流(AC)转化为直流(DC)的装置。它有两个主要功能：第一，将交流电(AC)变成直流电(DC)，经滤波后供给负载，或者供给逆变器;第二，给蓄电池提供充电电压。因此，它同时又起到一个充电器的作用;

7、机箱：机箱根据厂家做出的想对符合使用与美观的外形产品

5、 丰富的干接点监控信号，可纳入电厂自身的DCS监控系统;出现问题，及时上报，便于值班人员对UPS的实时监控。

电力科士达UPS系统一般由电力UPS主机、旁路稳压柜、输出馈线柜等三部分组成(小功率时也可三合一)。

1、电力科士达UPS电源主机柜：输入输出隔离变压器、整流器、逆变器、静态旁路开关、旁路开关、逆止二极管;

2、旁路隔离稳压柜：旁路隔离变压器、旁路稳压器、手动/旁路维修开关;

3、馈 线 柜： 回路分配单元、监测仪表、控制开关及信号指示等;

5. Inverter: Generally speaking, inverter is a device that converts DC into AC. It consists of inverter bridge, control logic and filter circuit.
6. Rectifier: Rectifier is a rectifier device, which simply converts AC to DC. It has two main functions: firstly, AC is transformed into DC, which is filtered to supply load or inverter; secondly, it provides charging voltage for storage battery. Therefore, it also acts as a charger.
7. chassis: chassis according to the manufacturer's desire to use and beautiful appearance products

3. Making full use of 220V/110V large capacity batteries in power industry can maximize UPS backup time and save installation space and investment in the future.
4. Select bypass isolation transformer to realize complete isolation between input and output, and ensure zero-ground voltage of output less than 1V.
5. The abundant dry contact monitoring signals can be incorporated into the DCS monitoring system of the power plant itself. If there are problems, report them in time to facilitate the real-time monitoring of UPS by the duty personnel.
Usually, the UPS system consists of three parts: power UPS host, bypass voltage regulator and output feeder cabinet.
1. The main cabinet of UPS power supply: input-output isolation transformer, rectifier, inverter, static bypass switch, bypass switch, backstop diode;
2. Bypass isolation voltage regulator: bypass isolation transformer, bypass voltage regulator, manual/bypass maintenance switch;
3. Feeder cabinet: circuit distribution unit, monitoring instrument, control switch and signal indication, etc.
Now when we go shopping, we can see emergency safety exit lights everywhere. Such lights will be driven by two power sources according to the regulations. One is normal power supply, the other is emergency power supply. Here we calculate that there are 1,000 such lights, totaling 2,000 w. How do I equip ups on the lamp of 2,000 w?

科士达ups不间断电源容量计算：

2000/0.8=2500VA

考虑到ups不间断电源容量的冗余，一般以20%到30%(因为UPS的最佳工作状态就是负载70%到80%);所以设计推荐UPS容量应该为2500VA X 1.5 = 3750VA，从而可以得出选用3750VA的UPS不间断电源

这样计算下我们得出3750kva。就可以使用3750kva 以上的ups不间断电源。那么已经得出了总的负载功率。当然这是我们诚稳电子的算法介绍，对于每个产品可能会有一些差异，但是这个区别不会太大。

Considering the redundancy of ups UPS capacity, it is generally 20% to 30% (because the optimal working state of UPS is load 70% to 80%); therefore, the recommended UPS capacity should be 2500VA X 1.5 = 3750VA, which can lead to the selection of 3750VA UPS uninterruptible power supply.
